Manufacturing Quality Control of 1-ANILINONAPHTHALENE-8-SULFONIC ACID AMMONIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase chromatography with UV detection at characteristic wavelength. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration based on iodine consumption in pyridine-methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual mass. |
| Heavy Metals (as Pb) | AAS | Quantifies total heavy metals via atomic absorption spectroscopy after acid digestion and matrix matching. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate anion using suppressed conductivity detection with carbonate eluent. |
| Chloride Impurity | Potentiometric Titration | Detects chloride by silver nitrate titration with silver/silver sulfide electrode endpoint detection. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in 1% w/v aqueous solution using calibrated glass electrode system. |
| Organic Volatile Impurities | GC-FID | Identifies and quantifies residual solvents using capillary column separation and flame ionization detection. |
| Color (APHA) | Visual Comparison or Spectrophotometer | Evaluates yellowness/brownness against platinum-cobalt standard scale using spectrophotometric absorbance at 430 nm. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension by analyzing angular scattering pattern of laser beam. |
| Bulk Density | Graduated Cylinder Method | Measures mass per unit volume of freely settled powder in standardized cylinder under controlled conditions. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
